ISRAEL L. LANDIS, OF CHICAGO, ILLINOIS.

STRUCTURE-GUARD.

SPECIFICATION forming part of Letters Patent No. 760,999, dated May 24,.1904.

Application filed November l1, 1902. Renewed November 6, 1903. SerialNo. 180,127. (No model.)

To LZ whom it may concern:

Be it known that I, ISRAEL L. LANDIS, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Structure-Guards, ofwhich the following is a specification.

This invention relates to guards for preventing abrasion from structuresbuilt of selfhardening plastic material-such-as cement, so-calledartificial stone, and the like-with particular reference to structuresexposed to the wear and tear of traiiic, such as streetcurbing.

This invention does not contemplate the broad idea of protectingartificial or natural stone curbing or similar structure with metalshields, which is exceedingly old in the art, nor corner-strips, norso-called metal clad or bound blocks, the object of the invention beingto provide a novel form of preferably metal-protecting plate havingsubstantially integral holding or anchoring means adapted to be built orworked into and upon and form a part of a curb or similar structurewhile the material is in a plastic state to receive the frictionalcontact of moving bodies and prevent the abrasion of the most exposedsurface or portion of such structure.

The invention consists generally in a curb, the most exposed portion ofthe vertical edge of which has been faced with a plate having a portionthereof embeddedl in said curb, said embedded portion being providedwith suitable anchoring means; and the invention further consists in thevarious details of construction and in combinations of parts, all ashereinafter described, and particularly pointed out in the claims.

My invention will be more readily understood by reference to theaccompanying drawings, forming a part of this specification, and inwhich- Figures 1, 2, 3, and 4 are vertical sections of curbing blocksprovided with different forms of protecting-plates, each embodying myinvention. Figs. 5, 6, 7, 8, and 9 are perspective views of thedifferent forms of plates and anchoring means.

Referring now to the drawings in detail,

numeral 2 refers throughout the various views to the protectingface-plate, presenting a Wearing-surface 3 on the vertical edge of thecurb structure 6, having a longitudinal portion projecting laterallytherefrom throughout its en' tire length designed to be embedded in thecurb while the latter is in its plastic state. Suitably disposed on andprojecting from the embedded portion 4 are the pins, lugs, orprojections 5 5, which provide the anchoring means and which may beseparate pins driven therethrough, as shown in Figs. 5, 7, and 8, orintegral lugs or projections cut out of and bent away from said embeddedportion, as shown in Figs. 6 and 9. Said embedded portion and itsanchoring means are designed to be built into the plastic material priorto hardening. Where separate pins are employed to provide the anchoringprojections 5 5, they may be of any desired form or length and insertedthrough the embedded portion 4 after the structure 6 has been partiallycompleted. I prefer, however, to cut and bend outwardly integralportions of the plate 4 to provide the anchoring means, as shown inFigs. 6 and 9.

The peculiar advantages of my invention over other forms of curbing andstructure guards lies in the fact that with slight changes common formsof commercial angle-iron and T-bars may be employed, the production ofspecial designs of plates being avoided.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. In a curbing, the combination, with anartificial-stone curb, of a guard comprising an angle-plate having onewing facing a portion of the vertical edge of said curbing and the otherwing being wholly embedded therein, said embedded wing being providedwith suitable apertures and separate anchoring means therein, wherebysaid embedded wing may be fastened to the curbing after the guard hasbeen placed in position.

2. In a curbing, the combination, with an artificial-stone curb, ofguard comprising an angle-plate having one wing facing a portion of theouter surface of said curb and the other wing wholly embedded therein,said embedded wing being provided with separate transverse pins wherebysaid plate may be inter- IOO locked with the curb after the guard hasbeen the guard has been partially embedded in the l O placed inposition. structure.

3. In a curbing, the combination, with an In testimony whereof I havehereunto set articial-stone curb, of a guard comprising an my h and inthe presence of two Witnesses.

angle-plate having one Wing embedded in the structure and the otherwing1 facing its outer ISRAEL L' LANDIS' face, the embedded wing beinganchored in Witnesses:

transverse pins adapted to be inserted after F. E. STEUART.
